One-third the weight of steel, aluminum locknuts resist corrosion in wet environments.

Titanium locknuts have a high strength-to-weight ratio and are resistant to acids and salt water.

Also known as Keps and K-Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

These locknuts have a curved washer that acts as a spring for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer.

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts.

Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments.

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.

More corrosion resistant than 18-8 stainless steel locknuts, these have excellent resistance to chemicals and salt water.

Grade F nuts are comparable in strength to Grade 5 bolts.

Choose these flange locknuts for their adherence to strict military standards for material and construction.

These untapped nylon flange locknuts form threads as they're tightened to resist vibration.

The nylon cap covers and grips the threads to resist loosening.
